YIELD AND SEED QUALITY AS INFLUENCED BY PRUNINGAND PLANT SPACING OF FRENCH BEAN

Abstract

The experiment was conducted at the research farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the rabi season from November 2016 to March 2017 to study the quality seed production of french bean as influenced by spacing and pruning. The experiment comprised of two of which factors, factor A. Pruning (P 0 = no pruning, P 1 = one time stem pruning, P 2 = two times stem pruning) and factor B. Spacing (S 1 = 30×10 cm spacing, S 2 =30×15 cm spacing and S 3 = 30×20 cm spacing). The experiment was conducted following the randomized complete block design (RCBD) with three replications. Result revealed that the number of pods plant 1 -1 (27.27), pod weight plant -1 (135.68 g) and pod yield (13.86 t ha ) showed the highest value resulting best seed yield (11.27 t ha ) due to pruning P 1 . Similarly, the number of pods plant -1 -1 (26.98), pod weight plant

(133.06 g) and pod yield (12.27 t ha 1 ) the wider spacing S 2 -1 ) attained the highest seed yield (9.97 t ha . Result also demonstrated that, seed quality (i.e. germination (%), shoot length and root length) was higher for the treatment P 1

and S 2 . Thus, the findings indicated that the one time pruning with wider spacing (30×15 cm) could be used for yield maximization of French bean in Bangladesh. - -1 -
